S4: The Lost Caverns of Tsojcanth (1982)
A module, I think, mostly remembered for being a mini-Monster Manual.
S2: White Plume Mountain (1979, 1981)
D&D’s first funhouse.
Fabulous Beasts and Demons (1975)
A study of the visual evolution of monsters.
Mysterious Monsters (1978)

The Hamlyn Book of Monsters (1984)

Monsters (1976)
An excellent example of a children’s monster book from the ’70s.
A Fantastic Bestiary (1969)
Perhaps an important inspiration for the Monster Manual.
